It's amazing how shallow the draft is on the Adventure. Here's some approximate measurements (including my 180 lb. weight):
Total draft (at drive well) with Mirage drive installed (folded flush) = 6"
Draft w/o drive = 4.5"
Waterline at well = about top of well
Waterline empty about 2" less
Waterline at seat scupper = top of scupper/bottom of seat area; scupper plugs advised unless heavy/choppy seas!
Top of seat scupper to hull exit = 2.5" (seating position pretty darned low for a SOT!)
Top of seat scupper to keel line (ie: draft at seat) = 3.75"
Hulls define the performance characteristics for any given boat. The Adventure's unique shape shows a marked evolution in design. It offers several advantages over the older hulls: 1) shallower draft; 2) better stability for a given width; 3) lower surfing/planing speed. As can be seen below, it looks like a cross between a canoe and a Sunfish (sailboat). Note the seams between the three distinct regions add rigidity and strength to the hull.
Here some comparisons of the latest design concepts compared with the earlier applications (early Mirage tandom for comparison). Not readily apparent is the straighter keel line (less rocker) for better tracking. The evolution is remarkable! (note: the pictures are not comparable in size; Tandom width = 34"; Adventure = 27.5)
Kudos to Hobie's design team for their continuing accomplishments!!
